PURPOSE Antiangiogenic drug treatment inhibits tumor growth by decreasing blood supply, which can also reduce the delivery of other therapeutic agents. Presently, we investigated the effect of the vascular endothelial growth factor receptor tyrosine kinase inhibitor axitinib (AG-013736) on tumor vascular patency and chemotherapeutic drug uptake. Furthermore, the effect of axitinib on the antitu...

To the Editor: The study by Lee et al. (1) is the first report on the effects of cancer chemotherapy on cognitive function in rodent models. Given the increasing concern about cognitive dysfunction in patients receiving chemotherapy, the development of animal models to characterize chemotherapy-induced cognitive impairment has been proposed as a priority for future research (2, 3). Unexpectedly...

The efficacy of preventive and organisational measures implemented in Italy to prevent the contamination of cytotoxic drug preparation rooms has been investigated, and oncologic wards of two Italian hospitals were examined. The sampling strategy was based not only on potential sources of contamination but also on responses to detailed questionnaires on workplace practices and work organisation....

cyclophosphamide (cp) is extensively used as an antineoplastic agent for the treatment of various cancers, as well as an immunosuppressive agent. however, despite its wide spectrum of clinical uses, cp is known to cause several adverse effects including reproductive toxicity. crataegus monogyna is one of the oldest pharmaceutical plants that have been shown to be cytoprotective by scavenging fr...

Gene therapy using the prodrug-activating enzyme P450 2B6 has shown substantial promise in preclinical and initial clinical studies with the P450 prodrugs cyclophosphamide and ifosfamide. We sought to optimize this therapy using the canine P450 enzyme 2B11, which activates cyclophosphamide and ifosfamide with Km of 80 to 160 micromol/L, approximately 10- to 20-fold lower than the Km of P450 2B6...

Ayurveda is an ancient science of life that uses a wide range formulations or herbal compounds to treat various diseases. Each drug must be scientifically, pre-clinically, and clinically evaluated in order gain global acceptance. As part the safety evaluation process, regulatory authorities around world require data on new genotoxic potential.MusalyadiChurna(MSDC) classical Ayurvedic formulatio...

The concept of polyherbalism has been highlighted in , an Ayurvedic literature dating back to 1300 AD. Polyherbal formulations enhance the therapeutic action and reduce concentrations single herbs, thereby reducing adverse events. In present study, clastogenic effect carwin capsuleshas evaluated against cyclophosphamide (CP)-induced chromosomal aberrations bone marrow cells mice. Genotoxicity w...

Diffuse large B cell lymphoma (DLBCL) accounts for nearly 40% of non-Hodgkin's lymphoma cases. The combined chemotherapy of rituximab, cyclophosphamide, Adriamycin, vincristine, and prednisone (R-CHOP) is considered as the standard therapy for DLBCL; however, nearly half of the patients become refractory to the R-CHOP regimen. Early identification of drug resistance and therapeutic failures are...

Tuftsin, a naturally occurring tetrapeptide with a sequence Thr-Lys-Pro-Arg was evaluated for its in vivo protective effect against cyclophosphamide-induced genotoxicity and oxidative stress in Swiss albino mice. The anticancer drug cyclophosphamide (CP) was administered intra-peritonially to induce mutagenic effect. The drug treatment caused significant increase in chromosomal aberrations, for...

The antitumor activity of Decalepis hamiltonii root extract (DHA) was investigated in Ehrlich Ascites Tumor (EAT) cell model in mice and the effect was compared with that of the anticancer drug, cyclophosphamide (CP). Treatment of EAT cell bearing mice with aqueous extract of Decalepis hamiltonii (50 mg/kg and 100 mg/kg b.w.) showed a significant reduction in ascites tumor volume, tumor cell co...
